To all 'whom 'it may conc-sfr.

le it knownthat l, SAMUEL lamine Meo FARBEN, a citizen oit he United States, residing at Pittsburgh, county of Allegheny, State oi leiinsylvania, have .invented a certain neitT and useful lniprovenient in h/lulticylinder Gas-Engines, and declare the ollowing to he afull, clear, and exact descrip-- tion of the saine, suoli as will enable others skilled. in the art to which it pertains to inalie and use the saine, ie'l'erence loeinghad tothe accompanying drawings, which i'orin part ot this specification. My invention relates to a multiple cylinder gas engine oit the radial. type, and the olibiect ot my improvements is to proviffle an in'iproved engine to reduce the vertical space. hitherto necessari ly occupied oy this type of engine, 'while .re-- taining@ the uniformity ot torque or turning,- efort and to secure zgreater stahility. l. secure this object in the device illustrated in the ecconi panyingdrawings, in which,

Figure Ll, is side elevation, partly in section, ot an engine embodying my inven lion. Fig. 2, some of the parts being partly broken away.

LAL, is the foundation; lil, Kl, are frames formed the arc of circles and stuiported on the Jfoundation L, lo, l here are two 'trames l and K1, in diilerent vertical planes.

ln the engine illustrated, the 'lour cycle inode of operation is used and tive cylinders are shown arranged in vertical planes. Upon the frame located 72 apart. ln these cylinders are pistons fil, BL, C1, coiniected hy connecting rods a, Y), c, with the crank pin g.

B 'and C and the cyleylinders i and B and at equal angular distances roin said cylinders. As in the 'tour cycle inode oiE operation, the sequence of events occurs in an angle ol" T203. 'lo secure uni-"torniity of toi-(pie, the successive, explosions niust occur in cylinders Mft@ from each other, that is, oi1elii`th of T20. .lhus in the arrangement shown, the sequence oli explosions would he as. ollowszcylinder A., cylinder C, cylin- .Y ind( il, and cylinder l).

lt `will he observed that in the above orin oiC engine, all 'the cylinders are located above a horizontal plane through the axis O the crunk sliziftor 'upon one 'Y of the shaft,

tween the cylinders side .niuch reduced and the cylinders are niade accessible and the-engine is more compact and stable; so that this type of engine is, hy my invention,-inade especially adaptable to vehicle or marine propulsion.

lWhile l have shown iny invention as applied to a vertical gas engine of the four cycle type, its adaptation to other engines will be obvious to those skilled iii the art.

L ln a four-cycle gas engine, a horizontally arran shaft provided with two cranks arrzin`v ed atI an angle of 180, three engine cylinders positioned at one side oi" the horizontal plane of' the shaft and in o vertical plane at right angles to the longitudinal exis of said sliai't, tivo similar gras. positioned on the saine side el? the shalt and in another Vvertical plane at right angles to the longitudinal axis of the shalt, p tons in all of said cylinders, 'pitiiien connecting` the pistons in the cylinders ot one group v'with one of the cranks of the sliaft,"pitiiien connecting the pistons in the other group of' cylinders with the other crank of the shaft, allot said cylin. ders heilig arranged'so as to produce iinpulses at equal angular intervals.

ln a gas engineol: the tour cycle typo, a horizontally disposed. shaft provided with tivo :lieufiiated cranks adjacent the ends .thermiit and arranged, atI an angle ot 11.800,

vioup oit radially.arranged gas engine gies to the plane ot' the longitudinal. axis of said shaft e.

of' rzuflial engine is .ud above the horizontal. plane a second group comprising ay different number of radially --arranged gas structed s ace therebetween, pistons in all of said cy inders, connections between the pistons of one group of cylinders and one of the cranks and connections between the pistons of the other group of cylinders and the other of4 said. Cranks, all of said cylinders being arranged so as to produce iinpulsesat equalangular intervals.

' 3. An internal combustion engine having an uneven nuinb'er of cylinders in two parallel groups, the cylinders of each group being arranged to make equal angles with each other, and a shaft having oppositely set cran ts, each of saidtwo groups of cylinders loeing` aboYe a horizontal plane passed through theaxis of said shaft, and the pistons of all of the Cylinders of one group being connected with one crank of said shaft, while those of the cylinders of the other group are connected with the other crank of said shaft.

et. An internal combustion engine having.

five o'ylinders.in two parallel groups, the Cylinders of each group being arranged to make equal angles with each other, and a shaft having oppositely set cranks, each of said two groups of cylinders being-above a horizontal plane passed through the axis of said shaft., andthe pistons ofall of the cylinders or one group 1oeing connected with'.

one crank of said shaft, While those of the an uneveunumber of cylinders in cylinders of the other group are `conneoted with the other crank of said shaft;

5. An internal combustion engine having two parn allel groups, a shaft vlraving oppositeljy set cranks-'each otY said two groups oteylinders he,` 1g above a horizontal plane passed through the airis of said shaft, pistons in u said cylinders, the pistons ot all of the Cylinders of one group being connected with one crank of said shaf'while those of the Cylinders of the other group connected with the other crank of said shaft, the oylinders of said groups being arranged to produce impulses atequal angular intervals throughout the Irevolution of the engine shaft. i

6. An internal combustion engine having ve Cylinders in two 'parallel groups, a shaft having oppositely set cranks, eaeli ot'said two groups of cylinders being above a horizontal plane passedthrough the axis said shaft, )istons in said e *linde-rs. the pistons l l 7 x.

of all of the Cylinders of' one group being connected' with one crank oi? sind sl while those of the Cylinders of .the oter group are Connected with the other crank of said shaft, all of said, oy'inders losing arranged to produce impulses equa-l angu lar intervals throughout the revolution of the engine shaft. l v l ln testimony whereof, l sign this speeincation in the presence of two witnesses.
